Hmm, I also got a few problems with Xara. Nothing major, I hope.
My "content" was out of date so, I updated. I downloaded and saved the file webdesigner 16_dlm.exe.
After installing this file, I still have no access to the extra content, it tells me I need to update again.
Shutting the "puter down and restart AND installing again, I still have the same result.
"Update Service Expired 22/04/2018" please up-date :-(

Any help appreciated
Cheers
